Abstract
Utilities supplied through a first utility path of a turning tool holder via a docking device is supplied to a second utility path of an adjacent rotating tool holder through a communication arrangement, there is no need to provide a complex hydraulic line, a pneumatic line and a coupler for receiving the utilities from the docking device at a rearward side of the rotating tool holder. A rearward size of the rotating tool holder may be minimized, so that even when the rotating tool holder is mounted on the turret, no interference occurs with the docking device in the rearward direction when the turret rotates. As a result, it is possible to use the rotating tool holder, to which utilities supply is necessary, even in the turret which is provide with the docking device.
Claims9
An apparatus for supplying utilities to a plurality of tool holders arranged in a circumferential direction of a turret of a machine tool, comprising:
- a docking device coupled with a turret body and including a docking device utility path capable of supplying at least one of utilities including a hydraulic pressure, a pneumatic pressure, and a coolant oil to a rear side of a first one of the tool holders, and the docking device further comprising an actuator for moving the docking device utility path;
- at least the first one of the plurality of tool holders being formed with a first utility path therein to receive the utilities supplied from the docking device when the docking device is aligned at a predetermined rearward position with the first one of the tool holders;
- a rotating tool holder of the plurality of tool holders, the rotating tool holder being installed on the turret in a circumferential direction adjacent to the first tool holder that is formed with the first utility path therein, the rotating tool holder being formed with a second utility path formed therein to receive the utilities from the first utility path of the first tool holder;
- and
- a communication means provided between the first tool holder and the rotating tool holder and forming an internal connecting path to connect the first utility path and the second utility path.
